Binge Size Rises With Body Mass Index in Bingeing Women
A DGReview of :"Binge size increases with body mass index in women with binge-eating disorder"
Obesity Research

Binge meal size increases with body mass index in women with binge-eating disorder.
During binge meals, the energy intake of people with binge-eating disorder is greater than that of people of similar body weight who do not have the disorder. It also correlates positively with body mass index, report researchers at St. Luke's/Roosevelt Hospital, New York, Columbia University College of Physicians and Surgeons, New York and the New York State Psychiatric Institute, New York.
To see if meal size was related to body mass index in obese people with binge-eating disorder, the researchers studied five groups who each consumed two laboratory-test meals on non-consecutive days.
The researchers instructed 42 women categorised by body mass index and binge-eating disorder diagnosis to "binge" during one meal and to eat "normally" during another.
Of these, 18 categorised as "more obese" had body mass index values exceeding 38 kg/m2. Of these, 12 met Diagnostic and Statistical Manual (DSM)-IV criteria for binge-eating disorder.
A further 17 women categorised as "less obese" had body mass index values of 28-32 kg/m2. Of these, nine met Diagnostic and Statistical Manual (DSM)-IV criteria for binge-eating disorder. The remaining seven women of normal weight women served as controls.
Women with binge-eating disorder ate significantly more in both meals than the other women. Binge meals were significantly larger than normal meals only among those with binge-eating disorder.
The more obese women with binge-eating disorder ate significantly more than the less obese women with binge-eating disorder, but only when they were asked to binge.
Intake of the binge meal was significantly and positively correlated with body mass index among those with binge-eating disorder.
Women with binge-eating disorder reported significantly higher satiety ratings after the binge than after the normal meal. In contrast, those who did not have binge-eating disorder reported similar ratings after both meals.
Regardless of instructions and diagnosis, obese women consumed a significantly higher percentage of energy from fat (38.5 percent) than controls (30.8 percent).
